starfire VLAN fix

Recognized VLAN ids are set via writew(), should go in host-endian.
That's a long-standing bug, BTW - see http://lkml.org/lkml/2004/2/27/180


for example.  What happens is that card gets VLAN id table populated by
byteswapped values on little-endian boxen (so 257 works as expected, 256
and 258 do not, etc.).  Bug is easily reproduced, patch fixes it.
